Welcome to Mikomoto Island, Japan — The Hammerhead Shark Capital of Japan!

At Loves Park Scuba, we are excited to continue our journey through the world's most extraordinary Pacific Ocean diving destinations.

Our eighth adventure takes us to one of Asia's most exciting shark-diving locations, where powerful currents and spectacular marine wildlife create an unforgettable experience.

1. Where Is Mikomoto Island?

Mikomoto Island, also known as Mikomoto-jima, is a small rocky island located off the southern coast of Japan's Izu Peninsula.

It belongs to Shizuoka Prefecture and lies in the Pacific Ocean, southwest of Tokyo.

The island is uninhabited and is famous for its historic lighthouse and the extraordinary marine life found in the surrounding waters.

What Makes Mikomoto Special?

Large schools of scalloped hammerhead sharks.
Powerful ocean currents.
Spectacular drift diving.
Dramatic underwater rock formations.
Large schools of pelagic fish.
Excellent opportunities for shark photography.
A fascinating combination of Japanese culture and ocean adventure.

Unlike tropical coral destinations, Mikomoto is dominated by rocky underwater landscapes and nutrient-rich currents.

Mikomoto is one of the most exciting hammerhead shark diving destinations in the Pacific Ocean!

2. The Hammerhead Sharks of Mikomoto

The greatest attraction at Mikomoto Island is the opportunity to encounter schools of scalloped hammerhead sharks.

These magnificent predators are recognized by their distinctive hammer-shaped heads.

Imagine the Ultimate Hammerhead Encounter!

You descend with your group near a rocky underwater formation.

The current moves steadily around the reef.

Your guide signals toward the blue water.

A hammerhead shark appears.

Then another.

And another.

Soon, an extraordinary school moves past the reef.

The sharks swim in formation, their silhouettes creating a spectacular underwater scene.

Why Do Hammerheads Visit Mikomoto?

Mikomoto lies in a region influenced by the warm Kuroshio Current.

This major Pacific Ocean current transports warm water and contributes to the movement of marine life through the region.

Hammerhead sharks and other pelagic species use these productive offshore waters.

What Is the Famous Hammerhead River?

Divers sometimes use the expression “Hammerhead River” to describe the extraordinary sight of large schools of hammerhead sharks swimming together.

Under favorable conditions, the number of sharks can be remarkable.

However, sightings are never guaranteed.

Observing a school of hammerhead sharks in the wild is one of the greatest experiences an advanced diver can have!

3. Kame-ne — The Legendary Hammerhead Diving Area!

One of the most famous dive sites around Mikomoto Island is Kame-ne.

This underwater rocky formation is internationally recognized for encounters with hammerhead sharks and large pelagic fish.

What Makes Kame-ne Special?

The underwater terrain creates a dynamic environment where currents flow around rocky structures.

Divers may encounter:

Scalloped hammerhead sharks.
Large schools of amberjack.
Yellowtail.
Other pelagic fish.
Sea turtles.
Rays.

The Diving Experience

Divers descend with their guides and explore the rocky formations while monitoring current conditions.

The guide selects the appropriate route based on the direction and strength of the water movement.

Important Considerations

Kame-ne is not a casual beginner dive.

Strong currents and open-water conditions can make the site demanding.

Kame-ne is one of the most iconic hammerhead shark diving locations in Japan!

4. A Point — A Spectacular Hammerhead Observation Area!

Another recognized diving location around Mikomoto is A Point.

This area is particularly associated with hammerhead shark encounters during favorable early-summer conditions.

What Makes A Point Special?

The underwater structure may provide opportunities to observe sharks moving through nearby blue water.

Marine Life Highlights

Scalloped hammerhead sharks.
Schools of pelagic fish.
Reef fish.
Other passing marine species.

Underwater Photography

A Point can provide opportunities for wide-angle shark photography when conditions are suitable.

Important Safety Message

Even when divers can observe sharks from a rocky formation, the surrounding current may be strong.

Divers must remain within their training limits and follow the guide's instructions.

A Point offers another exciting opportunity to experience Mikomoto's legendary hammerhead sharks.

5. Mitsu-ne — Dramatic Rocks and Massive Schools of Fish!

Mitsu-ne is another fascinating dive site around Mikomoto Island.

The area features distinctive underwater rock formations that attract numerous marine species.

What Can Divers Encounter?

Large schools of yellowtail.
Amberjack.
Other pelagic fish.
Reef fish.
Occasional sharks.
Rays.

What Makes Mitsu-ne Special?

The underwater formations create an exciting landscape for exploring marine biodiversity.

Schools of fish may gather around the rocky structures.

The Experience

Imagine swimming along a dramatic volcanic-looking rock formation while hundreds of fish move through the current.

Sunlight filters through the water, illuminating the underwater landscape.

Mitsu-ne demonstrates that Mikomoto is much more than a shark-diving destination!

6. Zabu-ne — Powerful Currents and Pelagic Encounters!

Zabu-ne is another recognized diving area around Mikomoto Island.

Its exposed rocky terrain creates opportunities for encounters with large marine animals.

Marine Life Highlights

Depending on conditions:

Hammerhead sharks.
Pelagic fish.
Schools of amberjack.
Yellowtail.
Other offshore species.

Why Is Zabu-ne Exciting?

The exposed environment and complex underwater formations create dramatic diving scenery.

However, conditions may be demanding.

Dive guides must evaluate current strength, visibility, and weather before selecting the site.

Zabu-ne offers experienced divers another opportunity to discover the wild underwater world of Mikomoto.

7. The Kuroshio Current — The Ocean Highway of Japan!

One of the most important natural features influencing Mikomoto is the Kuroshio Current.

This powerful western boundary current flows northward through the western Pacific.

It transports warm tropical and subtropical water along parts of Japan's coastline.

Why Is the Kuroshio Important?

The current influences:

Water temperature.
Marine species distribution.
Ocean productivity.
Pelagic fish movements.
Shark encounters.
Diving conditions.

What Does This Mean for Divers?

When the Kuroshio flows near Mikomoto, divers may experience warmer, clearer water and exciting pelagic activity.

However, the current can also create demanding underwater conditions.

Drift Diving in Mikomoto

Most diving around Mikomoto involves drift-diving procedures.

Divers must be comfortable with:

Boat entries.
Descending without fixed lines.
Maintaining group positioning.
Monitoring depth and gas supply.
Deploying a surface marker buoy.
Controlled open-water ascents.
Boat pickup procedures.

Understanding the Kuroshio Current is essential to appreciating both the excitement and the challenges of diving at Mikomoto.

8. More Than Hammerheads — The Marine Life of Mikomoto

Although hammerhead sharks are the main attraction, Mikomoto supports a remarkable variety of marine animals.

Amberjack and Yellowtail

Large schools of these powerful swimming fish are common attractions.

Barracuda

These streamlined predators may appear around offshore rocky formations.

Sea Turtles

Sea turtles are occasionally observed in the region.
